1 Claim.

This invention appertains to new and useful improvements in means for catapulting gas bombs or containers and the principal object of the invention is to provide a catapult which is electrically operated and capable of being remotely controlled to effect a discharge of a gas bomb in an effective manner.

Another important object of the present invention is to provide a gas bomb catapult especially adapted for use in banking houses and similar places where valuables are kept and which, in construction, is not readily observed so that its operation will be a surprise and an overcoming factor in the treatment of malfeasors.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure l is a vertical sectional view through the novel catapult.

Figure 2 is a horizontal sectional view through the casing of the catapult.

Figure 3 is an end elevational view looking toward the muzzle of the catapult with the dome removed.

Figure 4 is a fragmentary detailed longitudinal sectional View through a tool for removing and placing the gas bombs or cartridges.

Figure 5 is a fragmentary elevational view of the tool.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a base having a standard 6 thereon. Pivotally connected to this standard 6 is the body l having a bore 8 therein for containing the spring 9. The body I has a counterbore I6 for receiving the end portion a of the barrel I I, which barrel is provided with a stud I2 engageable into the bayonet slot I3 of the body I.

The barrel 1 I is provided with notches I4 at its discharge end and, as can be seen in Figure 1, a shoulder I5 is provided on the barrel and has a beveled side portion which can wedge against the body I with the stud I2 engaged in the slot I3.

Numeral It represents a raised portion on the body E supporting the bracket II upon which is mounted the electro-magnet I8. This electromagnet is adapted to actuate the armature I9 situated below the same, the armature being pivotally connected to the coupling member 29, which, in turn, is provided with a threaded socket for receiving the threaded upper end of the pin 2I. This pin extends through a bore 22 in the raised portion I6 and a spring 23 in this bore 1934, Serial No. 739,013

serves to normally urge the pin downwardly to engage the head 24 which has a circumferentially extending groove 25 therein for receiving the said pin 2I. The spring 9 impinges the head 24 and when the pin 2| is engaging in the groove 25 thereof, is under tension.

Numerals 2626 represent slotted and arcuate shaped arms which extend downwardly from the body I and through which the bolts 21 extend. Nuts 28 thereon can be tightened against these arms to maintain the body I in the proper adjusted position.

Wires 29 from the electro-magnet I8 extend to the socket 39 and all that is required is to plug in a current supply circuit with this plug socket 30 to accomplish the result desired.

Figures 4 and 5 represent a tool for inserting and removing the gas containers.

The tool consists of an elongated tube 29 provided with a fixed collar 30 thereon and a spring interposed between the collar 30 and a supplemental collar 3I. Numerals 32-32 represent slots in the tube and these slots at one end each have an offset 33 disposed in one direction and at its opposite end an offset 34 disposed in the opposite direction.

A cross rod 35 at one end of the tube 29 serves as a handle for the tool.

Itwill be observed that, in removing a cartridge after the catapult has been fired, the tube 29 is inserted into the barrel II with the teeth 35a on the supplemental collar 3| engaging into the notches I4 of the barrel II. Pressure is exerted until the tube 29 can be rotated so that the cross pin 35 through the collar 3| can engage into the offset 33 of the slots 3232. Now by rotating the barrel I I, the same can be disconnected from the bayonet slot I3.

In placing another bomb, the gas cartridge is inserted into the barrel II. The collar 3| is now permitted to go down to the offset 34 where the collar pin 36 is permitted to enter the offset 34. The tube 29 is now inserted into the barrel I I and the barrel inserted into the body 1. Thus the tool can be forced against the barrel I I to engage the stud I2 with the bayonet slot I3 without likelihood of damaging the gas cartridge or container.

Numeral 31 represents a dome of frosted glass or some similar material which is apt not to attract the attention of wrongdoers so that they will have an opportunity to damage the same before it can be placed into operation.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size,

and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A device of the class described comprising a pivotally mounted body having a bore therein, and a reduced cavity in the rear thereof communicating with said bore, a cartridge discharging hammer in said bore, a coil spring in said cavity, one end of said spring being secured to the body and the other end thereof to said hammer, said hammer being provided with an annular groove therein, a vertically and s1idably mounted pin in the top portion of said body adjacent said cavity, one end of said pin projecting into the bore in its innermost position, and adapted to ,1 ride in the annular groove of said hammer to maintain the same in cocked position, a coil spring normally maintaining the pin in said innermost propped position, an armature secured to the outer free end of said pin, magnetic means for actuating said armature to move the pin out of engagement with said hammer, said body adjacent its outer edge being provided with an arcuate shaped bayonet slot, the inner side portion adjacent the outer end gradually tapering downwardly and inwardly forming a cam surface, and a barrel having a projecting pin thereon receivable in said bayonet slot and a tapered shoulder cooperating with the cam surface of the body secured in said body, the free end of said barrel having spaced longitudinally extending notches therein.
